Abstract

Aspects of the present disclosure are directed to a methods and systems operable by a network entity for wireless communication, that includes determining that User Equipment (UE) is in idle mode and receiving eMBMS (evolved Multimedia Broadcast and Multicast Service); and based on the determining, activating a power optimization procedure in order to reduce power consumption of the UE. Examples of a power optimization procedures include a single or multi-level hardware shut down procedure, lowering the clock rate of hardware, and shutting down a communication bus during periods of non-use.

Claims17

Dependent claims

A method operable by a network entity for wireless communication, comprising:

determining, by a User Equipment (UE), that the UE is in idle mode and receiving evolved Multimedia Broadcast and Multicast Service (eMBMS);
receiving, by the UE, a schedule for eMBMS transmission;
determining, by the UE, a period of time in which the UE is expected to be idle based on the received eMBMS transmission schedule;
and
activating a power optimization procedure in order to reduce power consumption of the UE, wherein the power optimization procedure is activated based at least in part on the determined period of time, and wherein the activating the power optimization procedure includes:
activating a deep sleep when the determined period of time exceeds a first idle time;
activating a light sleep when the determined period of time exceeds a second idle time, wherein the second idle time is shorter in duration than the first idle time;
and
activating a micro sleep when the determined period of time exceeds a third idle time, wherein the third idle time is shorter in duration than the second idle time.

6 more elements

A non-transitory computer-readable medium having instructions stored thereon, wherein the instructions, when executed by a computer, cause the computer to:

determine, by a User Equipment (UE), that the UE is in idle mode and receiving evolved Multimedia Broadcast and Multicast Service (eMBMS);
receive, by the UE, a schedule for eMBMS transmission;
determine, by the UE, a period of time in which the UE is expected to be idle based on the received eMBMS transmission schedule;
and
based on said determination of the period of time, activate a power optimization procedure in order to reduce power consumption of the UE, and wherein the computer is caused to activate the power optimization procedure by:
causing the computer to activate a deep sleep when the determined period of time exceeds a first idle time;
causing the computer to activate a light sleep when the determined period of time exceeds a second idle time, wherein the second idle time is shorter in duration than the first idle time;
and
causing the computer to activate a micro sleep when the determined period of time exceeds a third idle time, wherein the third idle time is shorter in duration than the second idle time.

6 more elements

An apparatus configured for wireless communication, comprising:

at least one processor;
and
a memory coupled to said at least one processor, wherein the at least one processor is configured to:
determine, by a User Equipment (UE), that the UE is in idle mode and receiving evolved Multimedia Broadcast and Multicast Service (eMBMS);
receive, by the UE, a schedule for eMBMS transmission;
determine, by the UE, a period of time in which the UE is expected to be idle based on the received eMBMS transmission schedule;
and
activate a power optimization procedure in order to reduce power consumption of the UE based at least in part on said determination of the period of time, and wherein the configuration of the at least one processor to activate the power optimization procedure include:
to activate a deep sleep when the determined period of time exceeds a first idle time;
to activate a light sleep when the determined period of time exceeds a second idle time, wherein the second idle time is shorter in duration than the first idle time;
and
to activate a micro sleep when the determined period of time exceeds a third idle time, wherein the third idle time is shorter in duration than the second idle time.
